Yes, but it's potentially complicated.

First, are you using XQuartz or another build of (for example, from MacPorts)?  You'd presumably want to point the library path to the libraries of the one you're using.

I generally use XQuartz, so I do:

export DYLD_FALLBACK_LIBRARY_PATH=/opt/X11/lib:/usr/lib

The next question is whether you're running OS X 10.11 (El Capitan).  If so, its System Integrity Protection feature will make a nuisance of itself.  For security, it strips all DYLD_* variables from the environment when you run a "protected" executable.  All system executables are protected, including the shell interpreters.  If you are invoking a shell script such as the "wine" script for running Wine from the build tree, then that variable will be stripped.  For that particular case, you can put the export command into a .winewrapper file to have it sourced by the shell, which will work.  For other cases, you may need to edit your script.
